This paper presents a fatigue testing method using a multi-notched test specimen for the purpose of estimating the distribution function of fatigue crack initiation life by a small number...

Adaptive Reliability-Based Inspection Strategies for Structures Subject to Fatigue
Metallic structures subject to substantial load-induced fatigue must be inspected from time to time and, possibly, repaired or even put out of service if the damage has reached critical...

Objective Comparison of Fatigue Crack Growth Laws
This paper presents objective criteria for choosing between different fatigue crack growth laws to represent a material's fatigue behavior based on a data set containing multiple...

Fatigue Crack Closure Under Random Loading
The goals of the research are to determine fatigue crack growth rates for stationary random amplitude loadings with arbitrary mean stress. Fatigue crack closure theory is applied to justify...

An Investigation of Live Loads on Concrete Structures During Construction
Slab formwork live loads include the weight of equipment, construction material storage loads, and impact loads when placing the concrete. In this paper material and equipment loads are...

Probabilistic Approach to Stress Distributions for Orthotropic Wood Plates
Probabilistic approach to the stress distributions of an orthotropic wood plate is discussed. The stress distributions for the orthotropic elastic media are fully dependent of the material...

General European Principles of Codes Concerning Reliability
The requirements for reliability cover safety, serviceability and durability and consider different causes and types of failure. They may concern the occurrence of a failure or the duration...
